Sulfur fertilization optimizes maize yield through nutrient regulation and biomass responses in six contrasting soils of Northeast China.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Introduction: Sulfur (S) deficiency has re-emerged as a constraint to maize production due to reduced atmospheric deposition and the widespread use of S-free fertilizers. However, how S fertilization influences yield formation under contrasting soil conditions in Northeast China remains insufficiently quantified. Methods: Here, a two-year field experiment was conducted on six representative soil types using five S rates (0, 30, 60, 90, and 120 kg S ha Results: Across the six soils, fitted optimal S rates (61.4-89.7 kg S ha Discussion: Overall, under the studied conditions, S fertilization improved maize yield primarily through promoting early-season growth, nutrient coordination, and biomass remobilization rather than increasing post-silking assimilation alone. These findings provide a scientific basis for soil-specific sulfur management in temperate spring maize systems of Northeast China.
